科学技术文献出版社出版的《电工技术基础》(吕砚山主编)一书的附录中,简单地介绍了复数的算尺计算法。的确,在学习电工技术基础理论和日常进行的电工技术工作中,经常会遇到大量的交流电路的分析计算问题。对于同频正弦稳态交流电路的计算,利用复数符号法可以使电路的微分方程转化为复数的代数方程,将正弦量的加、减、微分、积分运算,转化 Science and Technology Documentation Publishing House published “basic electrical technology” (edited by Lu Yanshan) a book appendix, simply introduced the complex number calculation method. Indeed, in the study of basic theory of electrotechnics and daily electrical work, often encounter a large number of AC circuit analysis and calculation problems. For the calculation of sinusoidal steady-state AC circuit with the same frequency, the complex symbol method can be used to convert the differential equations of the circuit into complex algebraic equations. The addition, subtraction, differentiation, integration and conversion
